DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 through6 thereof, a new fan device embodying the principles and concepts of anembodiment of the disclosure and generally designated by the referencenumeral 10 will be described.

As best illustrated in FIGS. 1 through 6, the cooling fan assembly 10generally comprises a hub 12. The hub 12 has an outer wall 14 extendingforwardly from a back wall 16 of the hub 12. The outer wall 14 of thehub comes to a point at a front end 18 of the hub 12. Moreover, the hub12 has a bullet shape.

The back wall 16 of the hub 12 is coupled to a vehicle's water pump 20.The vehicle 22 may be a passenger vehicle of any conventional design.The vehicle's water pump 20 rotates the hub 12.

A plurality of blades 24 is provided. Each of the plurality of blades 24has a coupled end 26, a free end 28, a front edge 30 and a back edge 32.The plurality of blades 24 is each elongated between the coupled 26 andfree 28 ends. The coupled end 26 of the plurality of blades 24 is eachcoupled to the outer wall 14 of the hub 12. Moreover, the plurality ofblades 24 is evenly spaced apart and distributed around and entirecircumference of the outer wall 14 of the hub 12.

Each of the plurality of blades 24 is twisted along a longitudinal axisextending through the coupled 26 and free 28 ends of each of theplurality of blades 24. The free end 28 of each of the plurality ofblades 24 is curved between the front 30 and back 32 edges of theplurality of blades 24. Additionally, the coupled end 26 of each of theplurality of blades 24 is flat between the front 30 and back 32 edges ofthe plurality of blades 24. The coupled end 26 of each of the pluralityof blades 24 has a width that is greater than a width of the free end 28of each of the plurality of blades 24.

The plurality of blades 24 may collect and urge air at a high velocitywhen the hub 12 is rotated. Additionally, the plurality of blades 24urges the air at the high velocity through the vehicle's radiator 34.The assembly 10 improves an efficiency of the vehicle's radiator 34.

In use, a method 36 of increasing an efficiency of the vehicle'sradiator 34 includes a step 38 of providing the plurality of blades 24with the twisted shape that are each coupled to the hub 12. The method36 includes a step 40 of removing an existing fan 42 from the vehicle'swater pump 20. Finally, the method 36 includes a step 44 of coupling thehub 12 to the vehicle's water pump 20. The plurality of blades 24increases a cooling efficiency of the vehicle's radiator 34.

With respect to the above description then, it is to be realized thatthe optimum dimensional relationships for the parts of an embodimentenabled by the disclosure, to include variations in size, materials,shape, form, function and manner of operation, assembly and use, aredeemed readily apparent and obvious to one skilled in the art, and allequivalent relationships to those illustrated in the drawings anddescribed in the specification are intended to be encompassed by anembodiment of the disclosure.

Therefore, the foregoing is considered as illustrative only of theprinciples of the disclosure. Further, since numerous modifications andchanges will readily occur to those skilled in the art, it is notdesired to limit the disclosure to the exact construction and operationshown and described, and accordingly, all suitable modifications andequivalents may be resorted to, falling within the scope of thedisclosure.
